' y or' DELAWARE PATENT A." conroRA'r'IoN LIGHTNG FIXTURE his inventionv relates to certain new and useful improvements in lighting fixtures, and refers moreV particularly to means for ventilatingfthe interior thereof.

r Incertain"lighting fixtures, it is desirable that the lamp be totally enclosed and heretofore the lack of ventilation in such fixtures heated-its glassware to such anextent that very oftenY rain and snow caused it to crack.

i It is, therefore, an object ofv this invention to provide novel means for Ventilating the interior Vof lightingxtures of the character described. A Y

Another object of this invention resides i in the provision of meansfor Ventilating the interior of lighting fixtures of the 'characterv 'describedywhich is soi designed as to direct currentslof air across theflamp, and through and aroundA the refractor bowlto efficiently carry off the heat.

Another object of thisinvention resides in the'provision 0f novel meansfor mounting the refractorbowl of lighting fixtures of the character described, which permits the passage off air from the body of the fixture,

positioned beneath the refractor, into the interior of the refractor and around the exteriortliereof. f y

A further object of this invention resides "l inthe provision of a lightingfixture of the character described `including a protective globe having means providing an outlet for Ventilating currents of air, but preventingy entrance of rain and-moisture to the interior ofthe fixture. i i Anda still further object of this inventionresides inthe provision of an entrance and an outlet forlighting fixtures of the character described to provide ventilationifor the Ainterior thereof, and havingqmeans for preventing the entrance of .bugs and the like through said entrance and1 outlet.

l/Viththe above and other. objects in view A; which. will appear as the description proceedsyvmy invention resides 1n the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the ap- 0 pended claims, it being understood that such Vchanges inthe precise embodiment of the lustrated- 'tw-'oi `cornpl'etefexamples of the physical embodiment oflny invention con;k

from Vthe interior of the body'into the interior of the refractor and also around the exterior thereof.

The refractor mounting ring 13 is hinged to the body 5, as at 18, and islocked inclosed position by aconventional locking device 19 to permit thering together wit-h .its refractor to be swung to open position, as is customary. Therefractormounting ring 13 also carries a protective globe 20, whicln'together withy the mounting member A5,-totally*enclose's the entirefixture.

The apex ofthe Vprotective globe 20 hasan opening 21 therein whichgprovides an outlet for air entering the inlet 'openings 9 at the' y lowerend of the body .member and passing through theV fixture, over they lamp through the refractor 12the .upper end of Avwhich is open, as at 2,2, andaround.therefractor as illustratedby arrows in Figure 1. To prevent the entrance ofrain and moistureto they interior of the globe 20, the opening 21'is covered by aphood 2,3.which is maintained in spaced relation withfthe adjacent portion of f the globe by lugs 24 formedon the hood and f engaging the globe. The hood 23is secured in position by a stud 25 carried by the hood and passedthroughan opening 26` in aj spider like member 27 ,the outer ends of whose arms engage the inner surface of the globe, arnut 28fthreaded o n the lower end ofthe'stud 25 holding the hood andthe member 27 against ried by the ring 13 butis supported upon an annular flange 31 ,extended upwardlyfrom the innerportion of the body 5, and is maintained inposition by an annular inwardly directed flange 32 formedA on the ring 13 which engages the upper Side of the` annular bead 1,6

formed on the refractor bowl.,V .The manner j vof securing the hood 23- in positionA islikewisexsomewhat varied and the yspider like 1nember27isreplaced by aperforated washer However, the jmajor point of difference .exists inthe .manner of communicatingrthe interior ofk the body 5 with the atmosphere,

this being accomplished by drilling aholel in the supporting member 8, whichthrough the tubular supportingmember-7,.is in com'- munication 'with the interior y of' the. body 5.

f In this .formJ of my invention, the Ventilating current-of .air thus enters the-,holeh34`,. passes upwardlythrough the'supporting member7 and through the body 5.and around the globe,

through the refractor and then outwardly through the opening 21 in the apex ofthe f protective globe.

F rom the foregoing description,A taken'in connection with the accompanying drawings, it will beY readily. apparent v.to those. skilled acter described appertains, that I provide a novel means for ventilating'the interiorof lighting fixtures which in noway affects the designof the fixture and retains'v all ofthe desirable features of a totally enclosed fixe ture.
